Synthesis and antiviral evaluation of 2-amino-6-carbamoylpurine dioxolane nucleoside derivatives and their phosphoramidates prodrugs

Synthesis and in vitro Antibacterial Activity of Some Novel 2-Amino-4, 6-D Derivatives

Heterocyclic systems are one of the most important classes of organic compounds present in nature or synthesized in laboratory. These compounds posses an array of biological activities and are employed in the treatment of commonly occurring diseases. Keeping this in view, some new 2-amino-4,6-diarylpyrimidine from chalcones were synthesized. Eight novel 2-amino-4,6-diarylpyrimidine derivatives ...

Synthesis of Nucleoside Phosphate and Phosphonate Prodrugs

Synthesis Optimization of Some Nucleoside Analogues Derivatives and Their Antiviral Activity

To prepare the target nucleosides, the branched chain sugars was converted to their active form (1-bromosugar derivatives). This conversion included the hydrolysis of bromination with hydrobromic acid (HBr) in glacial acetic acid, forming 1-bromo sugars (4,6-di-O-Acetyl-2,3-dideoxy-3,3-di-C-nitro methyl-Darabinohexopyranosyl bromide), which were subjected to condensation with theophylline mercu...

Synthesis and Biological Evaluation of 4-hydroxychromenyl arylmethyl-6-hydroxy pyrimidine-2, 4-dione Derivatives

Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed ...

Synthesis and antitumor evaluation of novel derivatives of 6-amino-2-phenylbenzothiazoles.

Novel derivatives of 6-amino-2-phenylbenzothiazole bearing different substituents (amino, dimethylamino or fluoro) on the phenyl ring were prepared as the corresponding hydrochloride salts. 6-Nitro-2-(substituted-phenyl)benzothiazoles (1-6) were synthesized by condensation reactions of substituted benzaldehydes with 2-amino-5-nitrothiophenol. Nitro derivatives were reduced to the amino derivati...
